Trichomyia notata Araújo & Bravo sp. nov.

( Figs. 35A–G )

Diagnosis. Two pairs of expansions on gonocoxite, one apical truncated and with hairs and one basal hand-like; two pairs of arms of gonocoxite, one medial with bristles and one basal medially directed, with hairs; ejaculatory apodeme 1.9 times longer than the gonostylus; elongate cercus with three apical rod-like setae.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape subcylindrical; pedicel subspherical; basal flagellomeres pyriform and centric ( Fig. 35A ); ascoids 1.4 times as long as the length of flagellomere ( Fig. 35D ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.5 ( Fig. 35B ). Wing. R4+5 with unsclerotized base; r-m unsclerotized and mcu absent ( Fig. 35C ). Male terminalia: Hypandrium and gonocoxites fused with two pairs of expansions, one apical pair, truncated and with hairs and one basal pair hand-shape. Gonocoxites with two pairs of arms of gonocoxites, one medially, with bristles and one basal, medially directed, with hairs. Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare and subtriangular. Aedeagal complex with one pair of subtriangular projections. Aedeagus ending at midlle of projections in the aedeagal complex ( Fig. 35F ). Ejaculatory apodeme long, 1.9 times the length of gonostylus. Epandrium longer than wide. Cercus elongate and digitiform ( Fig. 35G ) with three apical rod-like setae ( Fig. 35E ). Hypoproct with apical micropilosity. Epiproct subcircular and membranous ( Fig. 35G ).
